His medical history is significant for severe chronic obstructive pulmonary disease (COPD) and a prior MI at the age of 58. After receiving aspirin, morphine, and face mask oxygen in the field, the patient arrives to the ED tachycardic (105 bpm), diaphoretic, and normotensive (126/86). A 12 lead electrocardiogram shows ST-elevation in I, aVL, and V5-V6. The attending physician suspects a lateral wall infarction. Which of following beta-blockers should be given to this patient and why?
